SUPPORT FOR DOOR-HANGER TRACKS.

SPECIFICATION forming part of Letters Patent No 357,969, dated February 15. 1857.

Serial No. 205,77i. (No model.)

To all whom it may concern.-

Be it known that 1, SIDNEY M. STEvENs, a citizen of the United States, residing in De Kalb, in the county of De Kalb and State of Illinois, have invented a new and useful Improvement in Supports for Door Hanger Tracks, of which the following is a specification.

It is necessary in the majority of cases, especially with barn door and similar hangers, to support the track or runway upon which the rollers travel by means of devices extending in a lateral direction from the track to the part of the building from which support is ob tained, and these devices must be such as to enable the track to be set at a sufficient remove from the building to avoid interference and friction between the moving devices and the adjacent parts of the building. Heretofore the track has been usually supported by horizontal screws, which pass through it into the building and draw the track firmly against interposed abutment -blocks adapted to afford the track such an amount of vertical bearingsurface as will keep it in line and prevent its turning or twisting or getting out of position. These blocks are not adjustable, must be taken out if the position of the track requires change, and must be reduced in size or larger ones substituted, according as the track needs adjustment toward or from the building.

In my invention I seek to provide a substitute for the wood or metal filling-blocks heretofore employed, which shall be capable of use with the ordinary supporting screws or bolts, and which, while it forms a square abutment against which the track may be drawn by the screws, will at the same time be adjustable and permit the track to be moved to or from the building, thereby rendering the adjustment a matter of great ease and saving much labor.

The invention therefore consists in thecombination, with the track and its supportingscrews, of an adjustable abutment, substantially as hereinafter set forth.

The invention also consists in certain details of construction of the adjustable abutment, also hereinafter set forth.

In the drawings, Figure l is a plan view of a portion of a track supported by my improved supports. Fig. 2 is a front elevation of the same. Fig. 3 is a transverse section on the line 3 3 of Fig. 1. Fig. 4 is an end view of the non-rotating nut. Fig. 5 shows the chair used to splice the joints in the track, being an elevation of the back thereof. Fig. 6 is a perspective of the parts forming the abutment. Fig. 7 is a plan of a modified construction of the abutment. Fig. 8 is a section of such modification on the line 8 8 of Fig. 7. Fig. 9 is a side view of one of the wedge-pieces used in said modification, and Fig. 10 is a plan, partly broken away,of a second modification.

In said drawings, A represents the barn or other building to which the track is applied, and A A represent sections of the track.

B B represent the customary bolts or screws by which the track is secured to the building, passing through the track into the building in the samemanner as heretofore. 7o

Interposed between the track and the building, and in such manner as to form a bearing against which the track may be drawn by the screws, and so held in its proper position without ability to twist or to rock on the screws, are my improved abutment-s, consisting of rotatable screws 0 and nourotatable nuts D. The former have heads 0 formed thereon, whereby they may be turned, and furnished with a broad surface in contact with the wood of the building, and the latter having projecting lips d at the front end, which engage with the track and prevent rotation. That portion of the end of the nut above the lip receives the pressure of the track. By making the screws 0 hollow they may be slipped over the screws B, as indicated. The abutment composed of the screw and nut permits the track to be moved to or from the building, as required, and allows very minute orconsid- 9o erable adjustments, as the case may require, and the adjustment, when made, is retained by simply tightening the screw B upon the track.

It also permits an old track to be adjusted without removing any of the parts, the only operations necessary being a slight loosening ofscre ws B, rotating the abutmentscrews, and

retightening the screws B.

When necessary, the nut D is beveled off at its upper front end, as shown at s, to avoid interference with the roller-flange.

\Vhile I have shown the abutment in use with a single-tread track formed of thin rails, it is obvious that it may be used with other forms of track.

Where the track is formed of more than one length of rail, as in the case illustrated, one of the abntments and an attaching-screw are located at the junction of the rails and a chair, E, employed in conjunction therewith. This chair is L-shaped in cross section, and is 'inserted with the lip'of the abutmentnut under 1t, while the ends of the track-rails rest'upon itsledge e. The attaching-screw passes through its vertical member, and its lower back corner is recessed, as at in, so as to let the lip set into it, and thus lower said ledge e to the proper horizontal plane to support the track. This construction renders the rail-joint very firm and holds the ends in such close union that neither can yield without the other. Thecliair can also be used throughout, if desired, for the purpose ofgiving the rail a wide support,and such may be desirable where wood tracks are used.

In the modification, Figs. 7, 8, and 9, the abutment is made of two wedgeshaped pieces, G G, having grooved and tenoned abutting faces, and elongated slots 9 for the passage of the bolts. The wedges are placed together,as

indicated, and the track is tightened upon them by the screw, as in the first-described form of the invention. The faces of the wedges which come into contact with each other are preferably corrugated, to prevent one part slipping upon the other. With this construction, it the track is to be adjusted away from the support, the wedges are moved toward each other, and if it is to be adjusted toward the building they are moved away from each other.

In the second modification the track is supported upon the bolts without the aid of any broad abutment bearing against the building. The boltin this case carries ajam-nut, H, and washer h, which are turned up against the building when the bolt has been properly adjusted. The track is held upright by the clamping action ofanoth er nut, K, upon its inside pressing it against the bolt-head.
